What are the running costs?
It goes without saying here that a Bentley tipping the scales at nearly three tonnes isn’t going to be cheap to run. It’s a case of relativity here, though. If you purchase a car priced well into six figures new, in theory you should also be able to afford to keep the thing on the road.
We’ll start with the the V8. Its figures make grim reading if you’re eco-minded, but then, we guess, green-minded people aren’t going to be looking at a new Bentley. Fuel consumption runs to 25mpg if driven gently. It’s helped considerably by cylinder de-activation technology – and in a week’s real-world testing, we slightly beat that figure, achieving 22.0mpg.
The Bentayga Hybrid has a 17.3kWh lithium-ion battery that gives an official all-electric range of up to 31 miles and can be charged in as little as 2.5 hours. With a mere 3.0-litre V6 under the bonnet, CO2 emissions are relatively parsimonious which means reasonably low BIK company car tax, although lesser SUVs such as the BMW X5 45e and Mercedes GLE 350de are in an even lower group.
On an 85-mile jaunt consisting mostly of motorway miles we averaged around 34mpg with a full battery. This figure would go up significantly if you were able to keep the engine switched off and run predominantly on battery power, something that’s more easily done if used mainly in urban environments.
Servicing and warranty
Bentleys come with a three-year unlimited mileage warranty.
It suggests regular maintenance and even offers a fixed price servicing scheme for cars over two years old. Interim services will set you back around £1,200, while smaller services are around £800. Bentley recommends servicing every 12 months or 10,000 miles.
Reliability
- Proving reliable in service
- Technology used elsewhere
- Great build quality and attentive dealers
With the complex engine options, you’d be forgiven for thinking the Bentley Bentayga’s reliability could be questionable, but the reality is it’s built using many parts from elsewhere in the Volkswagen Group (it’s based on the Audi Q7’s platform) so actually it should fare well. There haven’t been any significant recalls for the Q7 at all.
Furthermore, the build quality of the Bentayga feels exemplary. There were no indications of loose trim or rattles during our test drives.
